Do Industrial Incidents in the Chemical Sector Create Equity Market Contagion?

Abstract

Purpose: This paper examines a number of US chemical industry incidents and their effect on equity prices of the incident company. Furthermore, this paper then examines the contagion effect of this incident on direct competitors.Findings: This paper finds that the incident company experiences deeper negative abnormal returns as the number of injuries and fatalities as a result of the incident increases. The equity value of the competitor companies suffer substantial losses stemming from contagion effects when disasters occur causing ten or more injuries and fatalities, but benefit from the incident through increasing equity value when the level of injury and fatality is minor. Practical implications:This research can be used as a resource to promote and justify the cost of safety mechanisms within the chemical industry, as incidents have been shown to negatively affect the equity value of the not just the incident company, but also their direct competitors.

A relevância da fraude contábil ocorrida na Via Varejo S.A.: um estudo de eventos

Firm’s protection against disasters: are investment and insurance substitutes or complements?

“…Technological disasters are catastrophic events which result in contamination of the environment and lead to financial, environmental and human losses. They typically contain a greater threat to health than to property (Cutchin et al, 2008) and directly a↵ect firms' revenues by disrupting their production process, their stock (Capelle-Blancard and Laguna, 2010) and their equity prices (Brown et al, 2015). As a result, the economic implications of technological disasters are substantial and often catastrophic in their consequences (Pelling et al, 2002;Capelle-Blancard and Laguna, 2010).…”
